princerupe74, sorry, I was away yesterday. I had what was called a silent attack,no pain, but I knew something was wrong as I felt exhausted. The clinic sent me to hospital where I had the attack, again no pain. I then had an angiogram and the surgeon told me there were two arteries partially blocked. He then suggested as I was already on the table, to have them done then and there. I had no sensation of them being inserted and it seemed to take only minutes. After it was done I had to lie still for eight hours although I think that is now shortened to four hours. I was released the following day and was told not to drive for a week. I have never had any" tricky "moments since insertion. It was done in 1998 and for a few years afterwards I had six month check ups but this is now annually. I am still active and very grateful for the skills of the Surgeon. I hope this is some help to you, feel free to ask any other questions.
